Having PB2.5 as a downloadable client or having it on website doesn't make any differences. Also, that screenshot is just PB2's engine having problems with certain maps. It's rather not a general thing.
If it was then it'd be easier to start making cheats for the game. We had a big enough problem with some of the top 20 using cheat engine awhile ago, some never got caught.
